Dual trigger for semi-automatic rifle

Abstract

A dual trigger assembly for a rifle. The assembly includes the major components of the dual trigger and a trigger guard that is formed to accommodate the dual trigger. The dual trigger assembly may replace a single trigger assembly without the need for machining the rifle that will be provided with the dual trigger assembly.

What is claimed is: 
     
       1. A trigger for a semi-automatic firearm, the firearm for launching a bullet, the bullet initially carried in a cartridge, the cartridge containing a primer and a powder propellant, the primer and subsequently the powder propellant capable of being detonated by increased compression in the primer of the cartridge and subsequently increased compression in the powder propellant in the cartridge resulting from a hammer contacting a firing pin of the firearm when the hammer is released by actuation of the trigger, the trigger comprising:
 a trigger guard having a cavity in an upper section of the trigger guard for accommodating the trigger; 
 an upper portion of the trigger, the upper portion having a pivot location and a forward portion of the upper portion extending forward from the pivot location, the upper portion further having a rearward portion extending rearwardly from the pivot location; 
 an upper trigger bow for releasing the hammer, the upper trigger bow extending downwardly from the upper portion of the trigger, the upper trigger bow having a smooth rounded surface curved toward the rear of the upper trigger bow; 
 a transition zone extending downwardly from the upper trigger bow, the transition zone curved in a direction opposite the curve of the smooth rounded surface of the upper trigger bow, the transition zone curve providing clearance between the trigger and the upper section of the trigger guard when the trigger is at its fully displaced location; 
 a lower trigger bow for releasing the hammer, the lower trigger bow extending downwardly from the transition zone, the lower trigger bow having a smooth rounded surface curved toward the rear of the lower trigger bow, the lower trigger bow being vertically offset rearwardly relative to the upper trigger bow. 
 
     
     
       2. A trigger and trigger guard for use in a firearm, the firearm for launching a bullet, the bullet initially carried in a cartridge, the cartridge containing a primer and a powder propellant, the primer and subsequently the powder propellant capable of being detonated by increased compression in the primer of the cartridge and subsequently increased compression in the powder propellant in the cartridge resulting from a hammer contacting a firing pin of the firearm when the hammer is released by actuation of the trigger, the trigger comprising:
 a trigger guard having an upper section with a forward section and a transition section; 
 an upper portion of the trigger, the upper portion having a pivot location and a forward portion of the upper portion extending forward from the pivot location, the upper portion further having a rearward portion extending rearwardly from the pivot location; 
 an upper trigger bow integral with and extending downwardly from the upper portion of the trigger, whereby displacement of the upper trigger bow will displace the upper portion of the dual trigger and release the hammer, the upper trigger bow having a smooth rounded surface curved toward the rear of the upper trigger bow;
 a transition zone extending downwardly from the upper trigger bow, the transition zone curved in a direction opposite the curve of the smooth rounded surface of the upper trigger bow, the transition zone curve providing clearance between the trigger and the upper section of the trigger guard when the trigger is at its fully displaced location; 
 a lower trigger bow extending downwardly from the transition zone, whereby displacement of the lower trigger bow will displace the upper portion of the dual trigger and release the hammer, the lower trigger bow having a smooth rounded surface curved toward the rear of the lower trigger bow, the lower trigger bow being vertically offset rearwardly relative to the upper trigger bow; 
 the trigger guard further comprising an upper section with a forward section and a transition section and including a cavity of sufficient width and length to accommodate the transition zone of the trigger without contact between the transition zone of the trigger and the trigger guard and allowing the trigger to move laterally in the cavity during operation of the trigger; 
 
 the trigger guard having a valley section in the upper section of the trigger guard; and a trigger guard pin receiving through bore near one end of the upper section of the trigger guard and a push button receiving bore at the opposite end of the upper section of the trigger guard.
